NATHANIEL RETRUM, PA-C appears in the CMS NPPES registry as a Medical Physician Assistant provider holding PA-C credentials at 110 E 5TH AVE, ANTIGO, WI, 54409, with a listed phone of (715) 623-2351. NPI 1336548627 was issued on 08/22/2014. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what RETRUM most recently submitted to CMS rather than a vetted directory listing, which is why patients should always confirm the practice is still at this location before scheduling.

Medicare Part D records for calendar year 2023 show 2,225 prescription claims written by this provider, covering 327 Medicare beneficiaries and totaling roughly $193K in drug spend, split 9% brand-name and 91% generic by claim count, with an opioid prescribing rate of 4.0%. These figures capture only Medicare Part D — commercial insurance, Medicaid, and cash-pay prescriptions are not included, and any drug-beneficiary cell under 11 is suppressed by CMS for patient privacy. On the CMS Merit-based Incentive Payment System, this provider earned a Final Score of 76.9526/100 for the 2023 performance year (Quality 90.5283, Cost 25.227), compared with the national average of 83.1.

Medical Physician Assistant is a mid-sized specialty nationwide, with 40,527 enrolled providers across 55 states and an average of 1,077 Part D claims per prescriber, so the context for interpreting these metrics differs meaningfully from a primary-care baseline. Important: PlainDoctor is a directory of publicly available government data, not medical advice, a malpractice database, or a quality rating. Inclusion here does not imply a recommendation, and absence of complaints or sanctions on this page does not mean none exist — always verify credentials through the NPPES NPI Registry, your state medical board, and the ABMS or AOA before making healthcare decisions.
